Trump’s Policies

President Donald Trump talked about policies to boost the economy and lower taxes while softening his stance toward tariffs on China. The action has bolstered investors' confidence in the U.S. stock market. 

Trump took a call to slash the corporate tax rate to 15% from the current 21%, which would ignite business growth and investment in the United States. However, Trump will raise taxes on businesses outside of America, which would bring hundreds of billions of dollars – perhaps trillions of dollars – into the US Treasury and help to pay down America’s massive debt. The move will drive companies to make products in America, boosting U.S. manufacturing and labor market and thereby providing a boost to the economy.
 
Additionally, President Trump called OPEC to boost production and reduce prices as a way of bringing the Ukraine war to an end. He signed executive orders to bolster U.S. oil and gas production. These actions would reduce energy prices, thus lowering overall prices for American consumers. If oil price falls, inflation will drop. Reduced inflation will allow the Federal Reserve to lower interest rates.

AI Investments

Donald Trump announced a new joint venture called Stargate, which plans to invest $500 billion for building new AI infrastructure in the United States. ChatGPT creator OpenAI, SoftBank, and Oracle (ORCL Quick QuoteORCL - Free Report) will invest $100 billion in the project initially, with plans to pour up to $500 billion into Stargate in the coming years. The project is expected to create 100,000 U.S. jobs. Trump called it the “largest AI infrastructure project in history” (read: Trump Unveils Stargate AI Infrastructure Project: ETFs in Focus).

Solid Start to the Earnings Season

This reporting cycle is shaping up to be a good one for the market. Not only are companies comfortably beating estimates, particularly on the earnings front, but the growth pace represents a notable acceleration from the preceding periods. Total earnings for the 71 S&P 500 companies reported so far are up 19.2% from the same period last year on 6.7% higher revenues, with 83.1% beating EPS estimates and 67.6% beating revenue estimates. This is a better performance from the same group members than the other recent periods.
